In the last few years four-dimensional (4D) printing technologies have attained growing worldwide interest and they are
considered the "next big thing". The aim of this presentation is to provide three examples of stimuli-responsive polymer (SRP)
applications additively manufactured (AM) by the fused filament fabrication (FFF) technique and two examples of PLA based
shape memory polymer (SMP) applications. A CCT BLUE filament of thermo-responsive polymer was chosen to produce a
water temperature indicator, which changes the color when the temperature is increased; a CCU RED filament of photo-
responsive polymer was used to produce a sunlight / UV indicator bracelet; a transparent PLA CLEAR polymer, a CCU RED
photo-responsive polymer, and an electrically conductive PLA polymer were selected to produce a business card stand. A PLA
based filament of eSUN SMP was used to print two preliminary applications: a spring and a vase. We trust that these examples
will help to increase the interest in FFF 4D printed stimuli-responsive polymers and shape memory polymers possible
applications. Much R&D remains to be done in designing the objects and develop the FFF printing parameters taking advantage
of SRPs and SMPs being developed for this technology.

In his 2013 TED Talk (TED stands for technology, entertainment, and
design), Skylar Tibbits, the co-director of the MIT Self-Assembly Lab and
a pioneer of 4D printing, demonstrated how 3D-printed materials can
adapt to their surroundings (water, in his example)
